I think Bear is onto something, we already solved an analogous 
problem in an elegant way.

see SortedRange with assumeSorted etc.

But for this to be convenient to use, I still think we should 
expand the current 'String Literal Postfix' types to include both 
normaliztion and graphemes.

Postfix	Type	Aka
c	immutable(char)[]	string
w	immutable(wchar)[]	wstring
d	immutable(dchar)[]	dstring
